摘要：

The interaction of mercury vacancies with dopant indium atoms in Hg0.79Cd0.21Te was studied using the perturbed gamma-gamma-angular correlation (PAC) technique. Two dominant PAC signals, characterized by quadrupole interaction strengths nu-Q1 = 83 MHz and nu-Q2 = 91 MHz and asymmetry parameters eta-1 = eta-2 = 0.08, were observed and attributed to one or more In-V(Hg) complexes. The complexes appeared after annealing doped samples at T greater-than-or-equal-to 350-degrees-C in vacuum and quenching. The fraction of In atoms associated with vacancies was increased further by annealing at 80-degrees-C for > 10 h. The In-vacancy complexes vanished on annealing in a Hg-saturated atmosphere.
